TOZZZZ. whom itmai concern:

Be it known that I,

i gineer, subject of the'King of Sweden, re-

siding at Herserud, Sweden, have invented certain new and usefullmprovements in Electric Motor Cars, of which the following 7 is a specification."

Owing to the large space occupied-by the storage battery in electric .motor cars it has long been connected with difficulties to find :a'suitable place fort samef The result has been that manufacturers soften divide the battery, whicharrangement however is not v practical from the point of view of rapid-exchange of the battery. To facilitate such eXchange,t-he whole battery ought to be ar.-'

ranged in one-place onthe motor car; By arrangements hitherto known, fulfilling this condition, the motor car has obtained an ungainly appearance or the design, has resulted I other disadvantages. i a

The invention hasiparticularly for its'ob ject to provide a suitable place for the :battery, which place at the same time facilitates the designing and the building of the :body of the ear in full analogy with thatof other modern motor driven vehicles, such as gasoflene-driven cars, the characterizing feature of which consistsin thedriver s seat being located relatively low behind the! front wheels and in a.bonnet or hood being pro vided in front of-the drivers seat above the front wheels.

According to the present invention the battery is placed in the front part o'f 'th e motor'car in a horizontal or nclinedposrtion in such a manner, that the battery occupies, in addition'to the foremost' p neath the bonnet, corresponding to the place occupied by the engine in an ordinary petrol ca-r, also wholly or partly the space beneath the floor of the 'drivers place :and contingently alsoi beneath the drivers seat. 1f necessary,the battery room may extend also somewhat behindthe drivers seat. Preferably the'battery is arranged in 'asomewhat irrclined position, the foremost end with i enough clearance above the front axle,'-but. it

may; also *bejplaced in horizontal position. In the latter case, however, inconveniences arise'whlch are due, either, in case the bat te'ry is placed at a lowleveh -to the'l'lower 1 's'idef-ofthe battery being located too' close to'the front axle or, if the batteryis placed at a higher level, to thedrivers seat being located too high, whereby the motor car will i Specification of Letters Patent.

front part of the frame showing the location of the' battery box, and Figure 4 is a lon itu-.

dinal section of an electric motor car sio'wing the stepwise arrangement of the battery cells.

The battery box is carried by a' framework of an approximal parallel pi e(:lical form arranged in-the front part ofthe car between the two main frame-members a and b Fig. 2

carried by the front and rear'wheels. Said framework consists suitably of angle irons I connected together in the corners c, (l, e, f, g, h 2, and is fastened to the two main frame members a and b in such a manner that the lower longitudinal side bars k and Z of-the framework'and stays m and n pref- 'erably extending from the lowermost corsuitable way to the wheels.

- The motor is placed with its shaft in the longitudinal direction of the motor car for instance below the drivers seat and is preferably carried by the same frame construction that carries the battery. The motor should preferably be rigidly connected with the frame, but may also be hinged to the frame, particularly inlight cars.

7 By arranging the motorin this position it is made possible to use commonsingle spur gears :22, y. The'power istransmitted from these gears tov a propeller'shaft 2 and from this preferably through 'bevelgears in connection with the rear axle or in-any other By an'arrangement according to the inven tion, contrary'to most other designs'of electric trucks, also theadavantage is gained, that all easily damaged parts, such as the battery, the motor, the electric wiring, the controller and so on, are ntirely separated from the loading platform. In this way the design inthis respect becomes quite equal to thatof the petrol cars. fiIclaim:-"'
